bootc_disk: Add support for vmdk, ova

[cgwalters]

BIB PR using this: osbuild/bootc-image-builder#251

---

We want to support generating VMDK for bootc containers too.

[cgwalters]

So...I tried this out along with this patch for bib

And with that, I get this:

FileNotFoundError: [Errno 2] No such file or directory: 'qemu-img'

And yes, now I realize this is harder than I thought, because we need to either:

• Add that into our base images and assume its presence (eww)
• Add that into bib (edit: it's already there! thankfully), and rework the build pipeline to use the container as buildroot (I have no idea about doing this)

[cgwalters]

OK, if the remaining work is bib side and you think this is right - then lifting draft here.

See my in-line comment https://github.com/osbuild/images/pull/504/files#r1516881294

[achilleas-k]

Make pipelines run outside the build root.

Sorry for the confusion. I looked at the code before noticing the comment and it looked good but then realised the issue with the build root :)

[cgwalters]

OK yep updated, this generates an image! No idea if it works in vsphere yet, will ping about that.

Thank you! Let's land it as is and we (images team) will look into the suggested refactor (which makes a ton of sense) in a followup

This is addressed now, the pipeline runs now from the bib context.
